IMPROVEMENT IN MACHINES-FOR TRIMMING AND SETTING THE EDGES OF BOOTS ANDSHOES.

Specification forming part of Letters Patent No.'124,744, dated March19, 1872.

To all to whom these presents shall come:

Be it known that I, SAMUEL HORATIO HODGEs, of Lynn, in the county ofEssex and Commonwealth of Massachusetts, have made aninvention ofcertain Improvements in Ma. chinery for Trimming and Setting the Edgesof Boot and Shoe Soles 0r Heels; and do hereby declare the followingto'be a full, clear, and exactdescription thereof, due reference beinghad to the accompanying drawing making part of this specification, andin which Figure 1 is a plan; Fig. 2, a side elevation; Fig. 3, avertical section; and Fig. 4, a rear side view of the mechanism foractuating the heel and toe rest.

The subject of my present invention is a device for supporting a bootand shoe, and presenting it to the action of the trimming or burnishin gmechanism, such device being termed,

in machinery of this character, a jack. The

purpose of my present invention is to provide a jack of suchconstruction that the boot may be applied thereto and removed veryexpeditiously, and also enable the position of such boot to be variedwith respect to the trimming or burnishing tool, as occasion requires,in order not only that such tool shall be compelled to traverse theentire sole-edge, but to vary the transverse angle or slope of thelatter. The portion of my present jack which grasps the boot andsupports it in position while its sole is being trimmed or burnishedconsists of two horizontal posts or jaws, the longer of which is thetoe-rest, and supports the toe of the boot, the other being theheel-rest, which enters a socket in the last, the two supports slidingto and fro on parallel guides affixed to the outer face of an uprightdisk, and so operated, each by a screw which passes through it, and issupported within such disk and provided with a beveled pinion driven bya beveled annular gear, that, by the revolution of such screws travelingin opposite directions, the jaws or supports are compelled to approachor depart from each other, and either clamp the boot firmly between themor release it when the sole is finished, the ringgear being revolved bymeans of an annulus which surrounds and is H secured to it, and whichis-prov'ided at intertion in the arc of a circle of the clamping devicelast explained, and, in'so doing,vary the position of the soleedge withrespect to the trimming-tool, in order that a greater or less slope inextreme cases may be given to the toeand-heel portion of the latter,ascircumstances require, I mount the upright disk before named at its rearupon a segmental block, and unite beam being controlled by.anadjusting-screw in such manner as to vary the horizontal adjustment ofthe entire jack, with the exception of its standard, in order that, whendesirable,

the slope of the entire surface of the sole-edge may be varied.

The drawin g accompanyingthis specification represents at A a curvedstandard, which is to be pivoted or swiveled to the carriage whichsupports itin the machine to which it belongs,

such standard terminating at top in avertical column, a. B represents acircular plate or disk, to the outside of which is applied a dovetailedspline or way, 0, upon which slide two,

horizontalblocks or jaws, D E, one of which, D, is formed to receive thetoe of a boot in manner at once apparent to all shoe manufacturers,while the jaw E has a tenon, b, to enter a socket formed in the .lastnear its heel-end, each j aw being formed with an ear, 0, which enters alateral orifice ,or slot, cl, created in the center of the disk. Uponthe rear side of the disk B I dispose two twin-shaped screws, F orF,these screws being in longitudinal alignment with each other, anddisposed one upon each side of the center of the disk, and supported inbearings or lips e 0 formed upon such disk, while each screw carries atits outer end a beveled pinion, f, which engages with a beveled annulargear, g, which is disposed alongside of them,

rrrcn.-

or recede from one another for the purposes before stated; and in orderto readily rotate the annular gear g I inclose it within and securelyattach it to an annular concentric cap-plate or angular band, h, whichis' provided upon'its periphery with handles or knobs 11 t, &c.

Having thus seen the means provided for confining or jacking the boot,we will now explain the means of setting the jack at any vertical angle,in order that the slope of the toe-portion ofthe sole-edge, andalsoofthe heeledge, may be varied and determined at pleasure, it beingunderstood that the play of the jaws or disk is in a path parallel to orin alignment with the longitudinal plane of the said jaws. To carry outthis adjustment I affix to or form upon the inner side of the disk B ablock or housing, G, and in this housing I form a segmental dovetailedor shelf groove, H, which encompasses a segmental male tenon or spline,I, formed upon the outer face of a block, J, such block being swiveledhorizontally to a tilting or oscillating lever or beam K, whichsurmounts and is pivoted to the upper part of the column a. Thevibration or partial rotation of the disk B and its jaws upon the blockJ enables the angle of the toe-rest to be varied as occasion requires;consequently the revolving cutter or burnisher, whose horizontalposition is arbitrary, will reduce the edge of the toe-portion of thesole to an angle corresponding to that of the toe-rest. It will beobserved however, that as this adjustment or movement of the toe-rest isonly in a direction coincident with the common plane of the two jaws,and affects only the toe of the sole and the heel, it has no effect in acontrary direction, or upon the sides of the sole.

To obtain the necessary rotary motion in a vertical plane of the jack,or that portion of it comprisedinthe disk and its jaws and adjuncts, Ipivot such disk to the lever K, as stated. This pivoting of the diskenables the boot to be turned about upon an axis, which permits thero-.tary cutter or burnisher to travel entirely or partially around thesole, as the said cutter or burnisher is permitted afree play inavertical direction in order that it may follow the varying outline ofsaid sole.

In order to vary the general vertical slope of the entire jack for thepurpose of determining the slope of the side edges of the sole, and, incertain cases, where not much slope is required, of the toe and heelalso, without resorting to the segmental dovetailed connection beforenamed, I pivot or fulcrum the lever K horizontally to the column a, asbefore stated; and to control and adjust the position of this lever andof the jack I employ a vertical feedscrew, is, the upper part of whichis swiveled to the rear end of such lever, while its lower end screwsthrough a shelf or car, l, affixed to the column a, as shown in Fig. 3of the drawmg.

When adjusted in the desired position the disk B and its jaws are to beclamped or fixed to the segmental block J by a clamp or set screw, orany other proper means.- By pivoting or swiveling the standard A to itssupporting tablet or base I obtain a horizontal rotary or swingingmotion of the boot-sole with respect to the cutting or burnishin g tool,which enables such tool to follow all the curvatures of the outline ofsaid sole with respect to the upper.

With mechanism above described aboot may be jacked almost instantly, asa rapid movenieut is imparted to the jaws by means of the gear or rack gand pinions ff.

The compound or duplex adjustment of the jack is also a matter of greatimportance in machinery for trimming or setting edges of soles or heels.

My present jack will also be found valuable as a bench-jack, to whichpurpose it may be adapted with little change.

I do not confine myself to the dovetailed connection herein stated as apoint of vibration of the jack, as this vibratory union of the clampingportion of the jack with the rotary portion thereof may be effected invarious ways, such, for instance, as simply pivoting it to the block J.

Claims.
